Wire clamper for bonding apparatus

摘要

A wire clamper for a bonding apparatus includes a pair of clamper arms having tip portions, respectively. The tip portions clamp or release a wire therebetween when at least one of the clamper arms is operated. The wire clamper further includes a giant-magnetostrictive actuator having a giant-magnetostrictive alloy and a coil wound around the giant-magnetostrictive alloy for generating a magnetic field. The giant-magnetostrictive alloy is displaced according to the magnetic field generated by the coil so as to operate at least one of the clamper arms.
